Form is displaying as a mobile responsive jotform when set to 700px wide?

Hello,

My form is 700px wide, but when I view it on a pc, it is displaying as if it was on a mobile devices... it looks nothing like it does in the form designer?

You need to do these adjustmens:

Go to Setup & Embed Tab, then click on Preferences button.

On General Settings, set Responsive Form option to Yes

 While on Edit mode, click the Form Designer Icon on the Form Style toolbar. (Pictured below) 

On Form Layout click on Make This Form Responsive

This way the jotform shouldl be viewable on both mobile phones, pads and computers.

I hope this helps.
